ccna 100-105 pdf.288 Chapter 14 Implementing Frame RelayThe Frame Relay questions on the CCNA exam are a bit difficult for two main reasons. First, frame relay contains many optional settings that can be configured. Second, for network administrators who already have some experience with Frame Relay configuration, they may only have experience with one of the 3 main options for Frame Relay configuration (physical; multipoint or point-to-point), but the exam covers all of them. Therefore, in order to prepare for the exam, it is important to spend some time looking at the examples related to these options that are covered in this chapter.1. planning the configuration of Frame Relay Administrators must do a great deal of planning before they know where to start with the configuration. The following items must be considered when planning to add a new site. and related matters communicated to the Frame Relay provider. which in turn affect the Frame Relay configuration for the router. Determine which physical sites require a Frame Relay access link to be installed and determine the clock rate (access rate) to use on each link.Specify each VC by identifying the endpoints and setting the CIR.Use a consistent LMI type (usually specified by the provider).In addition, the administrator must select the detailed configuration based on the following options. and these items. the enterprise administrator does not need to consult the frame relay provider.. Select theIP subnetting scheme: all VCs - one subnet, each VC - one subnet, or one subnet for each full mesh interconnection subset.Select whether to assign IP addresses to physical, multipoint, or point-to-point subinterfaces.Select which VC requires the use of IETF encapsulation instead of the default value of "Cisco".IETF encapsulation is typically used in the case of non-Cisco routers.
